IMPROVEMENT iNYJolNTED oAns.

The Schedule referred to in these Letters' PatentV and making pit of thesame 4To 'all Iwhom it may concern:

Be it known that I, CHRISTIAN DANN, of La Grosse, in the county of LaGrosse and State of Wisconsin, have invented a` new and improved JointedOar; and I'do hereby declare that the following is a full,

'.clear, and vexact description thereof, which will enable othersskilled in the art to make and use the same,

. reference being had to the accompanying drawing forming part of 'thisspecification, in'whchv Figure 1 represents a perspective view ot' myi1nproved jointed-oar.

Figure 2 isa detail side view of the jointed part. A Similar letters ofreference indicate corresponding parts. My invent-ion relates tojointedoars' which are 'operated by a person facing the bow; and -'Ithas for its object toldisp'ense with metal cogs,

iihich rattle, produce great friction, are heavy, expensive, andconstantly acting to pull apartthe joint. For'this purpose I propose tocombine, with the ordinary pivoted handle, blade, and swinging plate, aexiblecord, fastened to the rounded and .pivote'd ends of the handle'and blade.

A B arethe two parts the 'oar,. being the handle and'B t-he blade.

These t-wo parts are, by means of pins wb, respectively pivoted to aplate, C, which, at-its ends, is pivoted into ears projecting 'from thegunwale of the boat. i

flhe contiguous or adjoining pivoted ends of the parts A B are connectedwith each other by means oi' a string or cord, c. Thus, it will'beperceived that the Aconstant; tendency of tbe joints will -be to cometogether, instead of being to separate; that the joint` worksnoiselessly; that the cord is readily'replaced in ease of accident orwear, and that the cost is but a small fraction of that of the coggedmetal pinions. Having thus described my invention, i I claim as new anddesire tosecnre byIJetters Patent- The combination, vwith a pivotedhandle,blad,and plate, A B Q, of ,the flexible cord c, fastened to therounded ends 4of the handle and blade, as and for the purpose'described. l

, CHRISTIAN DANN.
